Below "System Variables" there is a option for New, click it and add the following setting untill you reach the best mix of GPU useage.

Variable Name

FLUSH_INTERVAL

Variable Value

card 4870/4850 256 up to 512
card 3870/3850 128 up to 256

When done open a command window and type

echo %FLUSH_INTERVAL%

Then check your CPU, and GPU use to what it was previously. Tweak up or down according to your wants for performance and or system response.

This only effects ATI users, and only those with the new core, and only those that are seeing less then 80-90% GPU useage and a increase of CPU use.

In your environment, you can set FLUSH_INTERVAL to a value between 2 and 1024. This flag sets the maximum command packet size sent to the GPU. The default in the core is 16 which seems to solve the lag problems for most people, but at some added CPU overhead. People with higher-end boards can manually adjust this value until we deprecate this flag in later cores. The higher the value this flag is, the less driver overhead and lower CPU usage you will have, but there is still CPU optimization work going into later CAL releases and F@H cores. Setting this value to high will cause UI lag and potentially VPU recover and is designed more for advanced users. The lower the value, the smaller the command packet which translates into other graphics apps being able to play nice.

Not unless you are getting early unit ends. With mine at 1024 the first switch to a game caused the unit to bomb out. Anything more than 512 has no tangible effect on the speed of processing or the CPU load. So mine is set at 512, and I have no lag, and no issues running games at the same time.

To make the 4650/4670 fold; go to ATI website, searsh for SDK V1.2.1-beta.
you will be given a choice and you want to click the link to 'ati.amd.com/technology/streamingcomputing/sdkdwnld.html'.
after installing, locate your Folding@home-gpu folder and replace amdcalcl.dll and amdcalrt.dll with the new .dll files you just installed.
restart your pc. Good folding on ATI 4650/4670 cards.

Thanks, its up and folding, I really wanted to get it up and folding, since it is in my server which is the only PC on 24/7 in my house. So the HD4670 will be folding 24/7, I'm folding on my GTX260 now also, but not 24/7.

Sry Guys I have not been able to do any folding I lost a card and am waiting for the RMA, I also got my new motherboard so I am just waiting to change everything over just once. I should be up an folding this weekend...I hope.

OK, some of you may have seen this before. I'm posting this because we have new guy's on the team. I have the following Freehardware available to members of the folding team. My intentions are that you will fold with the free hardware(i.e...set up addt'l rigs). You have to be active folding for more than 30 days and in the Continental US. I will pay shipping, but you must return the hardware if you can no longer fold for TPU. All Motherboards are solid performers and offer as much PPD as today's boards. I may have addt'l hardware to get you going, depending on your needs. PM me if you are interested.
